I love George RR Martin and his devices. Margaery gets Tommen three kittens and Cersei goes on a four-page Rhaegar spiel because little Rhaenys had a black cat.

“Rhaenys would have been my daughter, if the Mad King had not played his cruel jape on Father. It had to have been madness that led Aerys to refuse Lord Tywin’s daughter.
The memory of the rejection still rankled, even after all these years.”

“Many a night Cersei had watched Prince Rhaegar in the hall, playing his silver-stringed harp with those long, elegant fingers of his. Had any man ever been so beautiful?
He was more than a man, though. His blood was the blood of old Valyria, the blood of dragons and gods.”

“Once Cersei had drawn a picture of herself flying behind Rhaegar on a dragon, her arms wrapped tight about his chest. When Jaime has discovered it, she told him it was Queen Alysanne and King Jaehaerys.”

“She was ten when she finally saw her prince in the flesh. The cheers of the smallfolk had echoed off Casterly Rock like rolling thunder.
They cheered Father twice as loudly as they cheered the king, but only half as loudly as they cheered Prince Rhaegar.”

“By night the prince played his silver harp and made her weep. When she had been presented to him, Cersei had almost drowned in the depth of his sad purple eyes.
He has been wounded, she recalled thinking, but I will mend his heart when we are wed.”

“Next to Rhaegar, even her beautiful Jaime had seemed no more than a callow boy.
The prince is going to be my husband, she had thought, giddy with excitement, and when the old king dies I’ll be the queen.”

“If she had only married Rhaegar like the gods intended, he would never have looked twice at the wolf girl.
Rhaegar would be our king today and I would be his queen, the mother of his sons.
She had never forgiven Robert for killing him.”
